A bucket tied at the end of a 1.6 m long string is whirled in a vertical circle with a constant speed. What should be the minimum speed so that the water from the bucket does not spill out during rotation (g= 10 ms2)?

A

9 ms-1

B

6.25 ms-1

C

16 ms-1

D

None of these

Answer

9 ms-1

Explanation

Solution

v = 5rg=5×1.6×10=9ms1.\sqrt{5rg} = \sqrt{5 \times 1.6 \times 10} = 9ms^{- 1}.
